GEASSES OF MICHAUX 's FLORA BOREALI-AMERICANA. 145 



Trichodium. laxifloriim Michx. 



" Cornuco'piae hy emails Walt. Hab. in pratensibus apricis a Canada ad Floridaru 

 [sign for male]." The specimen is Agrostis hiemalis (Walt.) B. S. P. 



Trichodium decumbens Michx. 



"Hab. in Carolina praesertim in unibrosis ripariis amnium. Trichod. (certissime) 

 majus Comucopiae perennans Walt." The specimen is Agrostis perennans (Walt.) 

 Tuckerm. 



Alopecurus aristulatus Michx. 



No specimen labeled with this name could be found, but there is a very poor speci- 

 men of an Alopecurus from which the spikelets have fallen, leaving the axis of the 

 spike, and this is labeled "Alopecurus breviaristatus Hab. in Canada adripas Lacus 

 Champlain legi [sign for perennial]." As Michaux's description states that the plant 

 has an erect culni and scarcely exserted awns, there is no doubt that the species is 

 Alopecurus aristulatus, as usually understood. 



Phaleris arundinacea L. 



The specimen belongs to this species. 



Phalaris villosa Michx. 



"'In Sabulosis Carolinae." The specimen is Anthaenantia villosa (Michx.) Beauv. 

 as usually understood. 



Paspalum setaceum Michx. 



"In aridis apricis Carolina, Georgia [sign for perennial]." Terminal spike single, 

 slightly curved; spikelets glabrous, 1.5 mm. long; blades pubescent. It belongs to 

 the species described under this name in Small's Flora. 



Paspalum debile Michx. 



"Hab. in Carolina [sign for perennial]." Blades densely woolly on both sides, 

 about 10 cm. long and 6 mm. wide; spike single, the culm smooth below the spike; 

 spikelets 1.5 mm. long, pubescent. This is Paspalum villosissimum Nash,° which 

 name should give way to that of Michaux. P. debile of Elliott's herbarium is P. 

 blepharophyllum Nash (P. debile Michx.; Ell. Bot. S. C. & Ga. 1: 105. 1816.) 



Paspalum ciliatifolium Michx. 



"In Carolina, Georgia." There are three specimens on the sheet. One without 

 spikelets may be eliminated from consideration, also one with pubescent spikelets, 

 since the description states that the spikelets are glabrous. The third specimen has 

 ciliate blades, these somewhat hispid above, more so below, upper sheath ciliate on 

 the margin; spikes 2; spikelets glabrous, 2 mm. long. This specimen, which I con- 

 sider the type, is in poor condition, but appears to belong to the species described 

 under this name in Small's Flora. 



Paspalum praecox Walt. 



"A Carolina ad Floridam." The specimen belongs to the species as described in 

 Small's Flora. 



Paspalum laeve Michx. 



"In Georgia." The specimen, consisting of a single culm with three short spikes 

 and smooth foliage, belongs to this species, as described in Small's Flora. 



Paspalum noridanum Michx. 



"Georgia et Florida.' 2 A single culm about 60 cm. high; lowermost sheath pubes- 

 cent, the remainder glabrous; blades short, the middle blades about 18 cm. long; 

 spikes 3, about 6 cm. long, erect, spikelets smooth, 3 mm. wide by 4 mm. long. This 



a In Small, Fl. So. States 73. 1903.
